Breast cancers along with a few cases of malignant melanomas displayed moderate to strong nuclear positivity. A fraction of cells in cases of ovarian, testicular and cervical cancers showed moderate nuclear staining. Remaining cancer tissues were mainly negative.
Cancer tissues displayed moderate nuclear and cytoplasmic immunoreactivity. Several cases of renal, cervical and ovarian cancers as well as a few cases of colorectal and gastric cancers showed strong nuclear staining. Most hepatocellular carcinomas were weakly stained.
The protein encoded by this gene is a transcriptional activator involved in cell proliferation. The encoded protein is phosphorylated in M phase and regulates the expression of several cell cycle genes, such as cyclin B1 and cyclin D1. Several transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2011]
